BROADCAST-SEED ER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 639,486, dated December 19, isles. Application filed fieptember 15, 1899. Serial No. 730,544. (No model.)

T0 at whom it may concern.-

Be it known that I, LINDLEY A. WRIGHT, of the city and county of Ohampaign, State of Illinois, have invented certain new and useful Improvements in Attachments for Broad cast Seeders, of which the following is a specification.

This invention relates to broadcast seeders in which a principal seed,as oats, forinstance, is thrown sidewise right and left by two centrifugal distributors or their equivalent and in which a secondary seed, as clover, is sup plied to each of the distributors in equal or nearly equal quantities. In seeders of this class one of the requirements is to supply the secondary seed in small streams continuously delivered without clogging the dischargeopenings, and this invention is intended to meet this requirement.

Heretofore each of the two distributors has been supplied from separate openings in the secondary hopper, which has necessitated two rather small openings, in which the grain has shown a tendency to clog; and it is the gist of this invention to supply the two distribu ters through a single comparatively large opening and to divide the stream of seed in its passage from the hopper to the distributors.

The invention resides, first, in aseed-stream divider located below a discharge-opening sufliciently large to supply two distributors with a proper proportion of secondary seed, and, second, in specific means for forming the divider. It is exemplified in the structure hereinafter described, and it is defined in the appended claims.

In the drawings forming part of this specification, Figures 1 and 2 are a front elevation and a side elevation, respectively, of a secondary seed-hopper constructed in accordance with my invention. Fig. 3 is a section on line Xi'n Fig. 2 through the discharge-outlet of the hopper, showing the preferred details of construction. Fig. 4. is a similar section showing a simplified form of streamdivider. Fig.

5 is a plan of the upper surface of a removable die having a discharge-opening and sup plied with a stream-divider. Fig. 6 is a plan of the under surface of the die.

Referring to Fig. 4, the hopper is shown at 6, the bottom thereof at 1, the discharge opening at 2, and the stream-divider at 3. The divider is in all cases a vertical partition set below the discharge-opening or the nar rowest part thereof a sufficient distance to permit the unobstructed passage of a stream of seed sufiicient to supply both of the seeddistributers, and in the case of the structure shown in Fig. 4 the divider is integral with the bifurcated chute for the divided stream, one leg of which is shown at 4 and the other at 5. This is a simplified form of the idea; but as it is desirable to vary the size of the discharge-opening 2 and as the dividing-partition 3 should always be directly under the center of the discharge-opening I have found it advantageous to make dies, as 7, each of which fits into a recess in the bottom of the hopper and has a discharge-opening larger or smaller than its fellows, so that a complete set of dies will provide openings of all required sizes. The dies each have a downward extended rim or flange, one-half of which is cut away, as shown in Figs. 3 and 6, and around the semicircle of the intact rim is bent a strip of thin metal 3, which in traversing the discharge-opening forms a stream-divider partaking of whatever side motion the die may have and always retaining its coincidence with a diameter of the opening.

The stream-divider should divide the seed equally. It is more certain to do this if its relation to the discharge motion is nicely and permanently fixed; but in the broadest sense of the invention I do not restrict myself to any particular means for holding the divider below and diametrically across the discharge opening.

What I claim is- 1. In a broadcast-seeder attachment, the combination of a secondary seed-hopper having a discharge-opening in its bottom sufficiently large to supply both sides ofthe seeder with the secondary seed, a bifurcated chute under the opening of the hopper, and a streamdividing partition fixed diametrically across the discharge-opening below the narrowest part thereof, whereby equal parts of seed may be supplied to both sides of the seed-distributer.

2. A seed-hopper, a removable die in the bottom of the hopper having a dischargeopening, and a stream-dividing partition on extended diametrically across the .dischar ethe under side of the die below the narrowest opening below the same. 10 part of the discharge-opening. In testimony whereof I sign my name in 3. A seed-hopper, a removable die in the the presence of two subscribing witnesses. bottom of the hopper having a discharge- LINDLEY A. WVRIGHT. opening, a semicircular rim on the bottom of Witnesses: the die concentric with the discharge-opening J. W. PORTER,

and a strip of metal attached to the rim and OLIVER K. DONEY.
